Calculate the amount of heat released when 27.0 g H2O is cooled from a liquid at 314 K to a solid at 263 K. The melting point of H2O is 273 K. Other useful information about water is listed below. Cp, liquid = 4.184 J/(g•K)

Cp, solid = 2.093 J/(g•K)

ΔHfusion = 40.7 kJ/mol

How many moles of H2O are present in the sample?

Which of these conditions most likely produces an unstable isotope?
